The article presents the field research data obtained in the foothill zone with the aim of assessing GHG emissions from arable light-dark chestnut soils while using different fertilizers, types of basic tillage, and crops. In accordance with the data presented, it can be argued that of the scientifically substantiated types of crops and soil cultivation methods studied within the framework of this research, all manure based options demonstrated high GHG emission values. The use of mineral fertilizers showed insignificant association between greenhouse gas emission reduc-tion and the no tillage option. Different crops showed varying degrees of GHG emission reduction depending on fertilizer application; yet, wheat responded most strongly due to additional biomass and yield growth. The research suggests the application of mineral fertilizers as a potential appropriate way to cut GHG emissions. However, further investigation is necessary to study the underlying mechanisms and processes influencing GHG and better understand the feedback effects in resource efficient (conservation) agriculture.","PeriodicalId":177314,"journal":{"name":"Central Asian Journal of Water Research","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122897928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The toxic element concentrations underwent comparison with background levels (Clark[e] numbers) and maximum permissible concentrations (MPC), with sub-sequent calculation of the total toxicity index (KHL). The study showed that practically all the inves-tigated rivers were subject to contamination, with uranium and lithium as the greatest contributors to surface water toxicity. The rivers in Southern and South-Eastern Kazakhstan – namely, the Kara-Balta, Syr Darya and Shu – were found to be most exposed. For instance, the KHL of the Kara-Balta River water exceeded the permissible threshold by over 5.9 times. The lowest KHL value (<1) corre-sponded to the Yertys and Ile Rivers.

The analyzed parameters included electric conductivity, pH, turbidity, odor, taste, color, hardness, as well as chloride (Cl2), nitrogen (N), fluoride (F), iron (Fe), arsenic (Ar), ammonia (NH3), and sulfide (SO4) content. All the analyzed chemical and physical parameters were found to be within acceptable limits. The results obtained were compared with the WHO drinking water quality standards. The study revealed that the values of physical parameters such as color, taste, odor and turbidity fell within the acceptable (recommended standard) limits; that the examined samples demonstrated no toxic elements and/or components; and that the analyzed chemical parameters were likewise within the permissible limits recommended by WHO and ANSA. Water quality in the target rural area proved to be better compared to the concerns of its residents and households, and that local water posed no threat to residents’ health and survival.

The most recent aerial imaging and single field surveys of the Lake Karakul Basin glaciation were carried out as late as in 1953. The investigation of the basin’s glaciers thus is of high scientific relevance, including in terms of glaciology and climatology. The article describes the calculations of the surface mass balance (SMB) of Glacier No.139 in the Lake Karakul Basin allowing, based on the findings, to assess the degree of climate change impact on the glaciation in the target zone, as well as the potential changes in the state of glaciers in the future. During 2018-2019, the mass balance of Glacier No.139, located in the basin’s southwestern section, amounted to -0.26 mwe. The data obtained from the Karakul Weather Station allowed establishing that the climate in the target watershed is harshly cold with little snow in winter and mild summer, and the bulk of precipitation occurring in the warm season. Due to the fact that in the past and until recently no glacier mass observations were conducted in the target zone, the research findings can serve as initial data to expand the scientific and applied knowledge, as well as contribute to enhancing the accuracy of glacier dynamics modeling in the area.","PeriodicalId":177314,"journal":{"name":"Central Asian Journal of Water Research","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121715186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Dust Retention Index is expressed in the dust mass that a unit of green tree mass can hold. The plant material was collected at three sites in Tashkent with different environmental conditions (sunlight, temperature, dust sources) for the following species: catalpa (Catalpa bignonioides Walt.), London plane (Platanus acerifolia), Eldar pine (Pinus eldarica), and cedar red juniper (Juniperus virginiana). The research shows that compared to coniferous species the following deciduous species demonstrate the highest dust retention values: plane (2.4, 1.2, and 13.3 mg/cm2, respectively), catalpa (8 and 3.6 mg/cm2, respectively), pine (0.185, 0.062, and 0.785 mg/cm2, respectively), and juniper (2.2 and 0.4 mg/cm2, respectively). The dust-retaining capacity was calculated based on the total dust emission in Tashkent averaging 24.6±6.9 thou. tons per year (2009-2018). Plane is capable of retaining approx. 0.61%, and pine – approx. 0.16% of the mean annual (2009-2018) aerosol mass (per 100 thou. trees). The calculations allow concluding that in order to compensate (retain) the annual dust emission in Tashkent, approximately 17-19 mln plane trees or 60-62 mln pine trees are necessary.","PeriodicalId":177314,"journal":{"name":"Central Asian Journal of Water Research","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114190895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Исследование основано на следующих показателях: демографические характеристики рождаемости, смертности (общей, младенческой, материнской), естественного прироста и ожидаемой продолжительности жизни, показатели здоровья населения, степень роста заболеваний, вызванных неблагоприятной экологией и суровым климатом в период с 2005 по 2019 г. Кроме того, с 31 августа по 10 сентября было проведено социологическое исследование местного населения в 15 населенных пунктах. Опрос охватил 120 человек, проживающих в Аральском районе Кызылординской области. На базе этих данных были определены ощущения жителей по их общему благосостоянию и состоянию здоровья. В ходе анкетирования и опроса установлено, что в изучаемой зоне жители довольны уровнем доходов, не связывают состояние своего здоровья с изменением климата, а также не желают мигрировать в другие регионы. То есть в исследуемом регионе миграция населения происходит преимущественно в связи с получением среднего и высшего образования и улучшением жилищных условий. Водообеспеченность региона не показывает значимые регрессионные связи с климатическими изменениями, что обусловлено установкой водокачек и доставкой питьевой воды на водовозах. Важнейшим выводом является то, что, вопреки ожиданиям авторов, в регионе согласно опросу жителей наблюдается стабильный рост численности населения за счет рождаемости, а также переселенцев. В Аральском регионе казахстанской части, по наблюдениям авторов, катастрофической ситуации не наблюдается.","PeriodicalId":177314,"journal":{"name":"Central Asian Journal of Water Research","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124196229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
